c++ - Verify static_assert in a unit test -


i make sure static_assert works should in unit test. is, if have 

class myclass {static_assert(my_type_trait<t>::value, "error"); };

then in unit test myclass<typewithtrait> myclass; should 'pass' , myclass<typewithouttrait> myclass; should 'fail'.

is possible this?

if want check fails compile, you'll have test external code. write simple file like:

#include "myclass.h"  int main() {      myclass<%t%> m; }

and write unit test compiles file different values of %t%. verify compilation either succeeds expected, or fails static_assert in failure text expected.
